A Morning with Malcolm the Skycrane

I went out flying yesterday, just a short flight to help a friend confirm the indicated airspeed he was reading on his recently completed RV-6A. I stopped and refueled after the flight, taxied back to the hangar and pushed the plane back into it’s parking spot. Just as I finished a stranger walked into the hangar and introduced himself. His name is Guy Keilman. His brother flies for the same airline that I do and mentioned that if Guy ever got to Stead airport he should look me up – that I have a Swift based there. Guy saw me taxi the Swift back to my hangar and was nice enough to walk up and say hi.

Erickson's Sikorsky Skycrane named Malcolm Guy is currently one of the pilots flying the Erickson Skycrane that is assigned to the Stead fire-fighting base this year. I say currently because he is actually assigned to fly from one of Erickson’s bases in Greece this summer. They operate on a 3-week cycle of work and free time and  just arrived back in the U.S. for his break. He was enroute to his home in Northern California when he got a call that they really needed him as a crew member at Stead for a few days. It was just a lucky coincidence that we met yesterday. We talked in the hangar for a while and then he said he’d be happy to give me a tour of the Skycrane. I jumped at the chance. Of course, I had to call my wife and let her know. She has watched the Skycranes operate from Stead for years and has always been fascinated with their size and capabilities. When she heard about the tour opportunity she dropped everything, jumped into the car and headed for the airport. If you are a Twitter user, you may recognize her as @yaksierra .

To say that the Skycrane is big is  a bit of an understatement. It is almost 90 feet long and it’s main rotor has a span of 72 feet – that’s twice the wing span of a C-172/182 or Beechcraft Bonanza.  Erickson names each of it’s Skycranes. The most famous is “Elvis” which made an appearance at EAA’s AirVenture last year (This year the crowd there is seeing “Goliath”). The Stead Skycrane this year is named “Malcolm.” Skycrane water tank and pond snorkle.

This photo is of the fire-fighting water tank that is attached in the area normally taken up by the winch/sling apparatus. As you can see, the tank holds up to 2650 U.S. gallons of water. The actual amount that they carry is dependent upon their fuel load, the temperature and the density altitude (sound familiar?). The fitting you can see in the middle of the aft ‘7’ is a fill valve for a 70-gallon foam tank. The foam can be injected into the water tank enroute to the fire. The foam is a detergent-based surfactant that, in effect, makes the water wetter.  The gray area at the bottom of the tank is one of the full-length doors in the fully open position.  The long hose is the pond snorkel. It has an electro-hydraulic pump at the bottom end that can suck water into the tank from any water source that is at least 18″ deep – and fill the tank in as little as 45 seconds. The tank can also be equipped with a sea snorkel that can be used to scoop up water while the Skycrane maintains forward motion – this eliminates the water spray up into the rotors that occurs when the filling process is done from a hover. The tank can also be filled with fire retardant very similar to that used by the fixed-wing tankers.  A control panel on the center console in the cockpit is used to set the amount and rate that the water is dumped.

There is also a water cannon that can be fitted to the left front of the Skycrane. It is capable of shooting a water stream up to 160′ to the front at a rate of 300 gallons/minute. It could be used to fight a fire in a high-rise building. You can see it demonstrated on the Erickson web site.

Skycrane Rear-facing Pilot Seat. This photo shows the rearward-facing pilot seat. The crew complement for fire-fighting is two pilots, however when the mission is heavy-lift construction (placing large items on construction pads or erecting tall towers) a third pilot is added to the crew. This third pilot sits at a station to the rear and below the main pilots. There is a clear view from there of the load suspended from the hoist/winch. When the load is to be placed into position this rear-facing pilot takes control of the Skycrane and can position the load exactly where it needs to go.

Sikorsky Skycrane cockpit. The Erickson fire fighting operation is day, VFR only which is reflected in the relatively sparse instrument panel that you find in the cockpit. Here you can see the control sticks (cyclic) at both seats and the collective for the right seat. One of those switches you see on the collective controls the pump at the end of the snorkel. The amount of water in the tank is indicated on a digital display in the top center of the left instrument panel. Right side windshield of Skycrane fire bomber. The center console is home to a lone Garmin 500 navigator and the VHF and FM radios. The FM communications band is used to talk with the fire fighters on the ground.  The right seat pilot on this crew used an ingenious method to keep track of all the information they needed when they were last dispatched to a fire. The bottom right block has all the Stead frequencies.

For those of you who subscribe to the idea that a helicopter is 10,000 parts flying in loose formation in an oil slick. Here is a photo of a large number of those parts – the main rotor mast head and transmission housing. Skycrane Main Rotor Mast and Transmission. The bell housing in the bottom is where the rotating turbine shaft of the right engine is changed to the other-direction rotating, flapping, twisting, retreating and advancing motion it takes to keep a helicopter in the air. I am not a helicopter pilot but if I were that would still look terribly complicated to me.  Maybe some of you helicopter pilots out there can make sense of all those moving parts.

Reno-Stead Fire-Fighting Base

There have been several thunderstorms in the area the past few days dropping huge amounts of water and spitting out lightning bolts. The lightning has started Air Tractor AT-802 fire fighting water bombera few fires in fairly inaccessible areas and has put our local fire fighters to work. There were two fire-fighting operations  on the east side of the Sierras last year, one in Minden, NV and our local one in Reno at Stead Airport. This year, probably due to budget constraints, only the Stead tanker base is in operation.

We have seen several different types of fire-fighting aircraft at our local base. This first photo is one of the two Air Tractor AT-802 aircraft that are used for the smaller fires. This one is sitting in front of the fire fighter operations building on the east end of our ramp. Lockheed P-3 Orion converted to fire fighting water bomberA few days ago I sat in my back yard and watched one of the Air Tractors and the P-3 Orion Tanker fly back and forth to a fire very near to where their Minden base used to be.; I walked out of my hangar yesterday and both of the Air Tractors flew overhead in close fingertip formation.

Our local base also is home to a Lockheed P2V Neptune that has been converted into a  water bomber. It was out making drops somewhere today. I caught it coming back for a refill as I was leaving the airport tonight. I heard it take off a couple of times, but never noticed the jet noise. Lockheed P2V Neptune converted to fire fighting water bomberThe big radials make the nicest sound anyway. The traffic pattern was pretty full today, but when one of the tanker aircraft needs to depart everybody clears out and lets them get to work.

The past few days we have also had a Huey helicopter, a twin Otter and two squads of fire jumpers/fire fighters staying on the airport. Their equipment identifies them as from the Boise BLM (Bureau of Land Management), probably on temporary duty in Nevada during our fire season.

The last of our resident fire fighting aircraft is the Sikorsky S-64  SkycraneSikorsky Skycrane fire fighting water bomber . It is operated by Erickson Air-crane based in Oregon. One of their other Helitankers (named Elvis) made a big hit at EAA’s AirVenture in Oshkosh, WI this week. The first video below is of their “arrival show” .

As great as it is to see all these aircraft fly, I really hope that this year they spend a lot of time just sitting around.
